In this article we investigate the frequency behavior of a ceramic capacitor.

We hope you enjoy the column and look forward to continuing the tradition of sharing these valuable stories.

The Industry 4.0 IoT platform automatically becomes a reliable and dependable venue for compliance verification, eliminating the traditional way of tedious predefined period manual checks.

The mirror technique is a very old technique to be used with PCBs when failing in radiated EMC tests. An easy solution to avoid changes in layout if the technique can be applied to your product.

This article discusses the crosstalk reduction between PCB traces by utilizing a guard trace between the traces and investigating the effect of the guard trace grounding.

Clock signals from 1 to 100MHz are usually responsible for radiated EMC problems in HF/VHF range. Harmonics are the culprits, but think in current, not in voltage.

Often (very) fast transients have been proven to trigger latch-up. This kind of latch-up is called transient induced latch-up, commonly known as “transient latch-up” (TLU).

We regularly receive requests from readers to publish stories about real EMI/EMC problems faced by real engineers.

For common-impedance coupling to occur, two circuits must share a current path (with a non-negligible impedance)

Inductive loads and interrupted currents are an explosive combination. High voltages, arcing, and HF broadband noise are some typical effects. The phenomena behind these transients is complex, but it is not difficult to understand the fundamentals and how to minimize the effects.
